Energy storage technology and its typical application in new energy grid connection system

Energy storage technology has always been an important lubricant for power systems, especially after wind power photovoltaics have been connected to the grid on a large scale. Energy storage equipment has played an active role in system peaking, frequency regulation, voltage regulation and accident backup. The article analyzes the development of different types of energy storage technologies at home and abroad, compares several common energy storage technology performance indicators, establishes an energy storage optimization model that maximizes the benefits of participating in system peaking and frequency regulation, and optimizes the operation. The local power grid is used as an example to verify the role of energy storage in providing climbing capacity, participating in system power tracking and frequency regulation, optimizing system operation, etc., giving recommendations for energy storage configuration, and for the application of energy storage in new energy grid connection Certainly guiding significance.
